Analyzing EEG Data: Lessons on Proper Data Handling and Labelling
In this video, I dive into the complexities of EEG data labelling and handling, highlighting common mistakes and best practices. I start by discussing the Kaggle competition and the data was collected from numerous patients. Using a custom tool, I demonstrate how we select EEG IDs, address issues with data repeats and anomalies, and provide insights on segmented data versus continuous data. Throughout the video, I emphasise the importance of proper data storage and labelling, share examples of expert consensus on labelling, and discuss the challenges of analysing EEG and ECG recordings. Watch as I troubleshoot and improve our data processing tool, aiming to make our analysis more accurate and efficient.
The tools I develop are available on https://bionichaos.com
